Timer1 library

Timer1 Library, I'm lost, I tried to use the analog write function but I can't get my motor to turn at speeds as low as 2.8 ms with the freq. standard in the Arduino. The devise which I am trying to copy delivers a freq. of 85 Htz with a pulse of 2.47 ms. I am trying to use the Timer1 library but I am Confused with the commands " pwm (pin,duty,period) ,and void pwm (char pin, int duty, long microseconds=-1), and void set PwmDuty(char pin,int duty); Need example on how to use and please no serial.
